title: Circulating osteocalcin in primary biliary cirrhosis following liver transplantation and during treatment with ciclosporin.
abstract: Circulating osteocalcin, a non-collagen bone protein is considered a useful indirect index of turnover. Osteocalcin levels were measured by radioimmunoassay in 57 female patients with primary biliary cirrhosis (PBC) from two centres, 52 normal female controls, 11 female patients following liver transplantation for PBC and seven female patients with PBC treated with Ciclosporin. Serum levels were significantly less in the PBC group (median 10 ng/ml) compared to normals (median 15 ng/ml: p less than 0.001). Patients with PBC treated with Ciclosporin had significantly higher levels than untreated patients (median 23 ng/ml: p less than 0.001). Levels also increased significantly following transplantation when all patients were receiving Ciclosporin (median 40 ng/ml: p less than 0.001). The results suggest that the abnormal bone metabolism of PBC is significantly altered by Ciclosporin and liver transplantation.
